Tom, Thanks for your help. It looks like these may be the same William T. Adams.The difference is the age of William T. in the 1900 census vs. the 1860, 1870 and 1880 census.
The 1870 Clarke Co. census Ward 1, Athens p 340 has Willam age 28, Mary age 25.a son the the person who wrote me said looked land Landford age 5.Could that be SANFORD and be your James Sanford.THat would have put him born about 1865. This person said that William and Mary were married about 1863/1864 which would fit with your William and Mary.Also the 1880 census shows her name a Mary Ann, same as yours.
If this fits, then your William T. is a brother to my Hiram Gaines Adams, sonof John C. and Faith Anne Dickerson Adams.
